### Lambda 表达式
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
Lambda 表达式可以在函数内定义，可以理解为在函数内定义的临时函数。格式：
|
||||
|
||||
```cpp
|
||||
auto func = []() -> return_type { };
|
||||
```
|
||||
|
||||
- `[]`为捕获列表，能够捕获其所在函数的局部变量
|
||||
- 一个空的捕获列表代表Lambda表达式不捕获任何的变量
|
||||
- 对于值捕获，直接在中括号中填写要捕获的变量即可：
|
||||
|
||||
```cpp
|
||||
int val = 5;
|
||||
auto func = [val]() -> return_type { };
|
||||
```
|
||||
|
||||
- 对于引用捕获，需要在捕获的变量前添加`&`：
|
||||
|
||||
```cpp
|
||||
string str("hello world!");
|
||||
auto func = [&str]() -> return_type { };
|
||||
```
|
||||
|
||||
- 如果变量太多，需要编译器根据我们编写的代码自动捕获，可以采用隐式捕获的方式。
|
||||
|
||||
- 全部值捕获：
|
||||
|
||||
```cpp
|
||||
int val1, val2;
|
||||
auto func = [=]() -> int
|
||||
{
|
||||
return val1 + val2;
|
||||
};
|
||||
```
|
||||
|
||||
- 全部引用捕获：
|
||||
|
||||
```cpp
|
||||
string str1("hello"), str2("word!");
|
||||
auto func = [&]() -> string
|
||||
{
|
||||
return str1 + str2;
|
||||
};
|
||||
```
|
||||
|
||||
- 混合隐式捕获：
|
||||
|
||||
如果希望对一部分变量采用值捕获，对其他变量采用引用捕获，可以混合使用：
|
||||
|
||||
```cpp
|
||||
int val1 = 123, val2 = 456;
|
||||
string str1("123"), str2(456);
|
||||
|
||||
auto func1 = [=, &str1]() -> int
|
||||
{
|
||||
return val1 == std::stoi(str1) ? val1 : val2;
|
||||
};
|
||||
|
||||
auto func2 = [&, val1]() -> int
|
||||
{
|
||||
return str1 == std::to_string(val1) ? str1 : str2;
|
||||
};
|
||||
```
|
||||
|
||||
- `()` 是参数列表，我们只需要按照普通函数的使用方法来使用即可
|
||||
- `return_type` 是函数的返回类型，`-> return_type` 可以不写，编译器会自动推导
|
||||
- `{}` 中的内容就是函数体，依照普通函数的使用方法使用即可
|
||||
<!--rehype:className=style-timeline-->
|
||||
|
||||
此处给出一个 Lambda 表达式的实际使用例子(当然可以使用 `str::copy`):
|
||||
|
||||
```cpp
|
||||
std::vector<int> vec({1, 2, 3, 4, 5}); // vec中包含1, 2, 3, 4, 5
|
||||
std::for_each(vec.begin(), vec.end(), [](int& ele) -> void
|
||||
{
|
||||
std::cout << ele << " ";
|
||||
});
|
||||
```

### Proxy
|
||||
|
||||
Proxy 对象用于创建一个对象的代理，从而实现基本操作的拦截和自定义（如属性查找、赋值、枚举、函数调用等）。
|
||||
|
||||
```javascript
|
||||
// 用于拦截对象的读取属性操作。
|
||||
const handler = {
|
||||
get: function(obj, prop) {
|
||||
return prop in obj ? obj[prop] : 37;
|
||||
}
|
||||
};
|
||||
|
||||
const p = new Proxy({}, handler);
|
||||
p.a = 1;
|
||||
p.b = undefined;
|
||||
|
||||
console.log(p.a, p.b); // 1, undefined
|
||||
console.log('c' in p, p.c); // false, 37
|
||||
```
|
||||
|
||||
#### 语法
|
||||
|
||||
```javascript
|
||||
const p = new Proxy(target, handler)
|
||||
```
|
||||
|
||||
- target 要使用 Proxy 包装的目标对象（可以是任何类型的对象，包括原生数组，函数，甚至另一个代理）。
|
||||

### Reflect
|
||||
|
||||
Reflect 是一个内置的对象，它提供拦截 JavaScript 操作的方法。这些方法与proxy handlers (en-US)的方法相同。Reflect不是一个函数对象，因此它是不可构造的。
|
||||
|
||||
```javascript
|
||||
// 检测一个对象是否存在特定属性
|
||||
const duck = {
|
||||
name: 'Maurice',
|
||||
color: 'white',
|
||||
greeting: function() {
|
||||
console.log(`Quaaaack! My name is ${this.name}`);
|
||||
}
|
||||
}
|
||||
|
||||
Reflect.has(duck, 'color');
|
||||
// true
|
||||
Reflect.has(duck, 'haircut');
|
||||
// false
|
||||
```
|
||||
|
||||
#### 静态方法
|
||||
|
||||
:- | :-
|
||||
:- | :-
|
||||
`Reflect.apply(target, thisArgument, argumentsList)` | 对一个函数进行调用操作，同时可以传入一个数组作为调用参数。和 Function.prototype.apply() 功能类似 [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/apply)
|
||||
`Reflect.construct(target, argumentsList[, newTarget])` | 对构造函数进行 new 操作，相当于执行 new target(...args) [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/construct)
|
||||
`Reflect.defineProperty(target, propertyKey, attributes)` | 和 Object.defineProperty() 类似。如果设置成功就会返回 true [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/defineProperty)
|
||||
`Reflect.deleteProperty(target, propertyKey)` | 作为函数的delete操作符，相当于执行 delete target[name] [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/deleteProperty)
|
||||
`Reflect.get(target, propertyKey[, receiver])` | 获取对象身上某个属性的值，类似于 target[name] [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/get)
|
||||
`Reflect.getOwnPropertyDescriptor(target, propertyKey)` | 类似于 Object.getOwnPropertyDescriptor()。如果对象中存在该属性，则返回对应的属性描述符，否则返回 undefined [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/getOwnPropertyDescriptor)
|
||||
`Reflect.getPrototypeOf(target)` | 类似于 Object.getPrototypeOf() [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/getPrototypeOf)
|
||||
`Reflect.has(target, propertyKey)` | 判断一个对象是否存在某个属性，和 in 运算符 的功能完全相同 [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/has)
|
||||
`Reflect.isExtensible(target)` | 类似于 Object.isExtensible() [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/isExtensible)
|
||||
`Reflect.ownKeys(target)` | 返回一个包含所有自身属性（不包含继承属性）的数组。(类似于 Object.keys(), 但不会受enumerable 影响) [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/ownKeys)
|
||||
`Reflect.preventExtensions(target)` | 类似于 Object.preventExtensions()。返回一个Boolean [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/preventExtensions)
|
||||
`Reflect.set(target, propertyKey, value[, receiver])` | 将值分配给属性的函数。返回一个Boolean，如果更新成功，则返回true [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/set)
|
||||
`Reflect.setPrototypeOf(target, prototype)` | 设置对象原型的函数。返回一个 Boolean，如果更新成功，则返回 true [#](https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Reflect/setPrototypeOf)

### 创建索引
|
||||
<!--rehype:wrap-class=col-span-2 row-span-3-->
|
||||
|
||||
```mongodb
|
||||
// 索引类型
|
||||
db.coll.createIndex({"name": 1}) // 单字段索引
|
||||
db.coll.createIndex({"name": 1, "date": 1}) // 复合索引
|
||||
db.coll.createIndex({foo: "text", bar: "text"}) // 文本索引
|
||||
db.coll.createIndex({"$**": "text"}) // 通配符文本索引
|
||||
db.coll.createIndex({"userMetadata.$**": 1}) // 通配符索引
|
||||
db.coll.createIndex({"loc": "2d"}) // 二维索引
|
||||
db.coll.createIndex({"loc": "2dsphere"}) // 2dsphere 索引
|
||||
db.coll.createIndex({"_id": "hashed"}) // 哈希索引
|
||||
|
||||
// Index Options
|
||||
db.coll.createIndex({"lastModifiedDate": 1}, {expireAfterSeconds: 3600}) // TTL指数
|
||||
db.coll.createIndex({"name": 1}, {unique: true})
|
||||
db.coll.createIndex({"name": 1}, {partialFilterExpression: {age: {$gt: 18}}}) // 部分索引
|
||||
// 强度为 1 或 2 的不区分大小写的索引
|
||||
db.coll.createIndex({"name": 1}, {collation: {locale: 'en', strength: 1}})
|
||||
db.coll.createIndex({"name": 1 }, {sparse: true})
|
||||
```
|
||||
|
||||
### 删除索引
|
||||
|
||||
```mongodb
|
||||
db.coll.dropIndex("name_1")
|
||||
```
|
||||
|
||||
### 隐藏/取消隐藏索引
|
||||
|
||||
```mongodb
|
||||
db.coll.hideIndex("name_1")
|
||||
db.coll.unhideIndex("name_1")

### 分片集群
|

### 副本集
|
||||
|
